Decision Analysis for the Evaluation of Risk in Nuclear Waste Management
本文提出基于决策分析的方法，通过开发辐射风险评价指标，解决核废料管理技术中社会风险的不确定性和社会价值融入问题，为监管提供清晰可辩护的基础。
The in~plementation of a nuclear waste management technology raises several issues concerning the regulation of social risk.The most basic of those issues are how to regulate a technology when the uncertainties in social consequences are important, and how to incorporate the relevant social values in the regulations.This paper presents a decision analytic approach to resolving these issues, based on the development of radiological risk evaluation indices.While it is essentially a case study, describing work carried out for the U.S. Nuclear Regulatory Commission, this case is used to discuss the more general issues involved.We begin by discussing the need for risk evaluation to provide a clear and defensible basis for regulating technologies involving social risk.W e then present an overview of the problem of evaluating the risk of nuclear waste management, and an overview of our approach.That is followed by a development of risk evaluation indices for the regulation of nuclear waste management.The indices developed are expected utilities, based on preferences elicited from groups of people.The use of the indices developed is illustrated in a hypothetical example.Finally, components of the analysis requiring further development are identified and discussed, and the usefulness of the methodology evaluated.
